To all of you know every things who are so darn informed about free software, why it is produced, and why progeCAD Smart! is available: the Free (progeCAD Smart!) is called charityware. A term invented by progeSOFT and not the first time they have produced software for charity. You can download and use it for free for non-commercial use, and if you like it, you are asked to donate to a worthy cause, doctors without borders for darfur.
